Abstract: Stethorrhagus tridentatus Caporiacco, 1955 Figs 8, 50 Stethorrhagus tridentatus Caporiacco, 1955: 379, fig. 47a–b, ♂. Stethorrhagus tridentatus – Bonaldo & Brescovit 1994: 49, fig. 14a–e, ♂ ♀. Diagnosis Males of S. tridentatus resemble those of S. peckorum by the DTA absent and by the medially inserted embolus (Fig. 8C–F; Bonaldo & Brescovit 1994: figs 14a–b, 22a–b). They differ by the tibia with AS short, inserted apically on vVL; embolus filiform, with long apical prongs (Bonaldo & Brescovit 1994: fig. 14a–b) (AS long, with wide base, inserted on tibial surface; embolus widened, flat and triangular, with reduced apical prongs in S. peckorum – Bonaldo & Brescovit 1994: fig. 22a–b). Females differ from those of other species with shallow sternal excavations (S. lupulus, S. oxossi and S. archangelus) by the absence of a VEP and by the dorsal plate with an accentuated V-shaped notch (Bonaldo & Brescovit 1994: fig. 14d–e) (VEP present; dorsal epigynal plate not notched in S. lupulus, S. oxossi and S. archangelus – Bonaldo & Brescovit 1994: figs 10f–g, 11c–d, 12d–e).
